Revealing mistake: During Lecter's escape, the SWAT team arrives and jumps out of the police car at the courthouse with their Ithaca 37 shotguns. All of them are shown chambering their rounds except the the officer on the right, who pulls back again on the fore stock and asks "ready?" That should've ejected a shell and left the gun unloaded. (01:21:40)
Other mistake: When Clarice goes to Crawford's office, she sees on the board a newspaper article titled "Bill skins fifth", but the article is not about Buffalo Bill. It's about Hannibal Lecter (his capture, the charges against him and so on). Nowhere is Bill mentioned. (00:05:50)
Continuity mistake: When Lecter is in the ambulance, wearing another man's face, as the ambulance officer has his back to Lecter, Lecter takes the large dressing off his face and pulls the oxygen mask down, then sits up, but when he does, the oxygen mask would be in the way; it is around his neck, he would have had to pull it over his head to get rid of it, but he didn't do this - the oxygen mask vanishes. (01:25:05)
Other mistake: Exterior views of Buffalo Bill's house showed the house was not very big and his yard space was limited. The amount of rooms, their sizes, and hall space purportedly in the basement were too excessive to believably be under that house. (00:49:20)
Continuity mistake: In the ambulance, after Lecter escapes, the towel on his face swaps from slightly bloody, to completely covered in blood between shots. (01:25:00)
Continuity mistake: In the very beginning, when Crawford calls Clarice in to talk about interviewing Hannibal, his left shirt collar is over his vest. Two shots later, the same collar is under the vest. (00:07:50)
Character mistake: Dissecting the chrysalis, Dr. Roden says that "Somebody grew this guy. Fed him honey and nightshade." Nightshade is indeed one of the typical plants eaten by the Death's head moth, but since "he" is only a pupa, would have not eaten honey, which is something only the adult specimen eats. (00:48:50)
Suggested correction: I don't see this so much as a mistake, but rather a shortcut so there would be no need to explain the entire metamorphosis process. Feeding "it" would refer to the larva stage, necessary to reach (grow to) the pupa stage. "It" may have transformed, but "it" is still the same "it." The men working there are experts and would know what he means, not interrupt and say, "Pupae don't eat, dumb @$$." Likewise, having to specifically say that someone fed the larva "honey and Nightshade" so that it would become that pupa doesn't seem to be necessary given the nature of the film. [And the larva - not just "adults" - might eat honey.].
Sorry, I don't really understand the point of the first part (like, 90%) of the correction; at no point I was disputing the concept of 'feeding a pupa', but just what it could have eaten to be raised to that stage. The only relevant part of your correction is that last phrase; "And the larva might eat honey." Which is not how it works from what I understand. If you want to correct this entry, please dispute that aspect; I never bred bugs (...on purpose!) and surely not of that kind, but the larvae of that species are strictly herbivores, and the honey plays into their diet only later in life - to the best of my knowledge they can't even process it at that stage. Assuming it can (which I have no particular reason to believe), it would be an exception and not what an entomologist would say to describe a well raised specimen. For what it is worth, also, Harris' novel never mentions honey, but specifically leaves, although it's a different plant.
Sorry if I misconstrued what you were trying to say. By writing that the pupa would not eat something only the adults eat, you left the impression that the pupa eats other things (just not the honey). I think I understand now. Your answer is specific to the honey and my response addressed how much information the experts needed to present about metamorphosis and food/no food to the audience. I hope this helps you understand at least some of that 90%.
Continuity mistake: Lecter asks for a lamb chop dinner, rare, and when they arrive, they are rare. When we see them later, they look well done. (01:15:50)
Suggested correction: They don't look different in any of the shots. It's the same lambchops, same temperature. They are cooked as is, so they have a dark outside but inside they are probably rare. They do look darker in the last scene but that's probably because they have gone cold and dried out.
Suggested correction: How would a mistake like that come to be? Someone cooked them in between shots? Too much time elapsed and the substance oxidized? The potato and everything else on the plate look the same, and so do the chops, shape-wise. They might be of a slightly darker color in the very last shot with Boyle on the floor, but the plate has also been sprayed with blood, so that could account for this - mostly perceived - change.
A mistake like this would come to be if they're using real food and not props and had to do a cut, change camera position, do a reshoot, etc and had to set the scene again and redo the cooking of the food, or remake the props for some reason, but now the food looks different. What we see as a continuous scene in a movie or TV show is not always done in one take, which is why the site is filled with countless continuity mistakes.
Continuity mistake: Before Lecter takes the towel off his face in the ambulance, a bunch of tubes suddenly appear all over his chest and waist, between shots. (01:24:55)
Character mistake: Clarice was given clear, explicit instructions by Crawford before going to the asylum to see Lecter, including: do not touch the glass; do not approach the glass; tell him nothing personal; do not accept anything from him. Barney also gave the specific rules to Clarice when she got there (e.g, "you don't get near the glass"; use the food tray carrier to give him papers), and informed her he would be watching her on video. An FBI Agent TRAINEE is under close scrutiny and failure to meet the high standards and/or rigorous training can/will result in dismissal from the academy; a student must follow the rules and demonstrate she has what it takes to graduate and is suitable to become a member of the FBI. Given the high standards and relative difficulty in securing a position with the FBI, a trainee would not blatantly break the rules or virtually disregard the direct orders of a supervisor like Clarice did - especially during the very first assignment. The end does not justify the means.
Continuity mistake: When Lecter is in the Memphis jail cell, trying to escape, there is a shot of him eating the face of Sgt. Pembry, and a nano-second later, you see Lecter trying to completely shove the jail door on him. No way these two events could have transpired so quickly. (01:15:50)
Factual error: When Starling leaves from Memphis, the jet shown taking off is in St Louis, not Memphis. This can be noted by not just the McDonnell Douglas sign, but the fact that the sign is on their Headquarters Hangar, which is in St. Louis. I have lived in St louis all my life: there is no mistaking this sign and building (even in the dark) for another hangar or sign in another city. It also helps to know McDonnell Douglas had no hangar in Memphis, nor any buildings with any signage at the time of the movie at all.
Character mistake: When the scientists cut open the cocoon found in the throat of a murder victim, they are not wearing gloves even though Clarice specifically states that it was found behind the soft palate of a murder victim. (00:48:00)
Plot hole: When Clarice visits Lecter in his new makeshift cell, she brings his drawings, which were left behind in Baltimore. She tells him how she saw the lambs being killed and heard them screaming, taking one lamb with her when she ran away. As the guards approached his cell after she leaves, the camera pans across the cell, taking in the drawings Clarice had brought, and the top one is a very detailed drawing of Clarice holding a spring lamb. She only told just told Lecter about the lamb, not enough time for him to have done that drawing.
Suggested correction: First; I do agree and support the mistake. But playing devil's advocate for a moment; she told him back in Baltimore about the ranch and how they had sheep and horses, so in theory he could have already started drawing back then and figure that a memory about the place was linked to those animals, adding the exact detail afterwards. Should also be noted that the guards approach the cell 'after she leaves', yes, but it's an 'after' that happens after she already flew back all the way from Memphis, so a few hours later.
Your last sentence corrects the mistake, the top drawing is new and wasn't brought by Clarice. You can see chalk on top of the drawing indicating he had just made it. Several hours passed between her delivering her story and him receiving his dinner.
Continuity mistake: When Lecter is about to kill the two cops guarding him, he kicks the cell door preventing one of the cops from entering the cell. Just a moment later he is in front of the guard and there is no metal door in between them.
Revealing mistake: When Clarice goes to Crawford's office, on the board there is a newspaper article titled "Bill Attacks Again, Woman Missing..." on the left and another titled "FBI Links 'Skinning..." on the right. The three top paragraphs on the left columns of both are identical (with different spacing). Two of the yellow lines on the right one are the same too.
Continuity mistake: Before Clarice chases Buffalo Bill down the basement steps, she quickly slips off her green overcoat, letting it fall to the floor. (I wasn't able to see if the green/red checked blazer and/or the grey scarf she almost always wore were slipped off at the same time - the view was obstructed by a table.) After Bill is killed, Clarice exits the house and comes down the front steps wearing the green/red checked suit jacket (blazer), but does not have the green overcoat or scarf with her. (01:43:13 - 01:50:17)
Continuity mistake: On ground floor in Memphis, the female police officer says "No, nobody went up." Sgt. Tate at this point starts to croak something, and behind him as shots as heard one of the men behind him is walking forward. The feet of that person are in the circular section of the floor decoration, but in the next shot both policemen coming from that direction are a couple steps behind that spot. (01:18:50)
Continuity mistake: The two guards approach Hannibal's cage and put down the tray with the lamb dinner. Lt. Boyle murmurs "Wonder what he wants for breakfast." He is passing the club to Sgt. Pembry holding it with his right hand on the tip. In the next shot, when he finishes quipping "Some damn thing from the zoo?" his hand is on the opposite end of the baton, past the handle. (01:15:10)
Continuity mistake: Clarice is at the desk of the Courthouse in Memphis. She hands the ID to the agent, who holds it with both hands. Cut, and he's holding it with just the right hand. The female agent next to him in the second shot is leaning against her own left hand, but she had both on the desk in the first shot. (01:05:30)
